Question

What is the slope of the line that contains the points (4 -1) and (-1,4)

Answer 1

-1

Explanation:

Use the equation for slope.

`m=(y_(2)-y_(1) )/(x_(2)- x_(1) )`

Plug in the given points into the equation.

`m=(4-(-1) )/(-1- 4 )\\m=(4+1 )/(-5 )\\m=(5)/(-5 )\\m=(1)/(-1 )\\m=-1`

The slope is -1.

Answer 2

-1

Explanation:

The slope formula when given two points is

m = ( y2-y1)/(x2-x1)

= (4 - -1)/(-1 -4)

= (4+1)/(-5)

= 5/-5

=-1
